California-based online travel booking website CheapAir.com has announced that it has completed more than $1.5m in bitcoin sales on flights, hotels and Amtrak bookings via its platform.

With the announcement, CheapAir joins Overstock as the second traditional e-commerce player in the bitcoin ecosystem to reveal that it has completed more than $1.5m in sales. Overstock disclosed that its figures topped $1.6m in May.

Speaking to CoinDesk, CheapAir CEO Jeff Klee suggested that the numbers are a testament to the loyalty of bitcoin users who have remained committed to the company even in the face of new competition.
